Listed at the very top of a nutrition label, “serving size” is the first thing you’ll see. The serving size is a number with a measurement, such as cups or ounces, that tells you how big one serving is based on that food. Directly below the serving size you’ll see “servings per container,” which tells you how many of those servings are in that package of food. The serving size and servings per container are there to help you decide how much of the food you should eat. Be aware that all of the nutrition information on the label is based on one serving.
